由于对接华为的一个项目，需要将我们的服务放到tomcat中以war包方式发布，有了这两天的工作。

本地测试tomcat 使用的版本：8.5.58，下载地址

https://tomcat.apache.org/download-80.cgi

项目发布war包：

1、修改pom：

修改打包方式：

war

让内置Springboot内置的tomcat失效：

    org.springframework.boot    spring-boot-starter-tomcat    provided

添加servlet-api的依赖

    org.apache.tomcat    tomcat-servlet-api    8.5.58    provided

添加failOnMissingWebXml配置，不用生成一个无用的Web.xml 文件

                                org.apache.maven.plugins           maven-war-plugin                           false                         

修改启动类，让启动类继承SpringBootServletInitializer   并重写configure 方法

@SpringBootApplicationpublic class BsApplication extends SpringBootServletInitializer{/*** 入口方法* @param args*/   public static void main(String[] args) {      SpringApplication.run(BsApplication.class, args);   }   //增加的方法   @Override   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder){       return builder.sources(BsApplication.class);   }}

将项目打成war包，将target目录下的war文件复制到tomcat的webapp中，运行tomcat。在window上部署：

没有问题的话，在http://localhost:8080/manager页面可以看到，此时就可以启动ui工程来连接服务了。

部署中遇到的问题

控制台输出错误太简洁不好定位

Tomcat启动报错：一个或多个筛选器启动失败。由于之前的错误，Context[]启动失败

在项目的WEB-INFO/classes 目录下添加 logging.properity 可以在logs中的 error-debug.log里面看到详细的报错信息。

handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandlerorg.apache.juli.FileHandler.level = FINE  org.apache.juli.FileHandler.directory = ${catalina.base}/logs  org.apache.juli.FileHandler.prefix = error-debug.java.util.logging.ConsoleHandler.level = FINE  java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

问题1：

Failed to execute goal com.github.wvengen:proguard-maven-plugin:2.3.1:proguard (default) on project ****-server: Obfuscation failed (result=1) -> [Help 1]

有两种方法:

一、使用命令 mvn clean install -Dproguard.skip=true 打包，该方法治标不治本。

二、修改

<injar>${project.build.finalName}.jarinjar>

为

 <injar>${project.build.finalName}/WEB-INF/classes/injar>

(原来打包输出为jar包，现在打包输出为war)

问题2：

Fix：定位到代码的一个Filter类中注解使用不当。改改就可以了，得兼容两种情况，一个是支持华为的war包，一个是其他项目中的jar，代码需要考虑兼容性。
